In the present study we call attention to the close connection between languages and globalization and we emphasize the importance of the Internet and online websites in foreign language teaching and learning as unavoidable elements of computer assisted language learning (CALL). Most of the educators can notice the traditional teacher-centered teaching model has been unable to cater for the present...
OpenFlow is a Software Defined Networking (SDN) paradigm that decouples control and data forwarding layers of routing. In this paper, we propose OpenQoS, which is a novel OpenFlow controller design for multimedia delivery with end-to-end Quality of Service (QoS) support. Our approach is based on QoS routing where the routes of multimedia traffic are optimized dynamically to fulfill the required QoS...
In this paper, we propose a novel approach for cross-modal multimedia retrieval by jointly modeling the text and image components of multimedia documents. In this model, the image component is represented by local SIFT descriptors based on the bag-of-feature model. The text component is represented by a topic distribution learned from latent topic models such as latent Dirichlet allocation (LDA)....
In recent years, Internet of Things (IoT) has become the hottest issues of Future Internet. It is the most important concept of Future Internet for providing a common global IT Platform to combine seamless networks and networked things. However, there is a lack of common fabric for integrating IoT with current Internet. That results the service providers and operators have no definite specification...
In this paper, we investigate the proxy video caching problem and propose a specific caching replacement strategy for segmented video streaming. The proposed caching algorithm makes use of the natural linear time structure of video streaming, which fits the philosophy of the optimal MIN algorithm. By observing the watching positions of active viewers at a certain point of time, the replacement approach...
As the Internet technology has been growing up fast; Internet has been used as a common infrastructure widespread. The broadcast environment has been also changed with transmission network expanded to Internet. TV is no longer than a passive device to receive a signal of terrestrial television broadcasting and it is evolving into a smart device providing Internet-based services. The evolution made...
The NGN concept is implementing on the operator networks by SoftSwitch platform and IP Multimedia Subsystem (IMS) platform up to now. The functional requirements and architectures were determined at ITU-T recommendations Y.2012 and Y.2021 for SoftSwitch and IMS respectively. Both of these platforms have the accomplishments and limitations. The Distributed Service Network (DSN) became a new platform...
This paper aims at discussing the creation and use of an Interactive Multimedia Resource (RIMult) to support teaching and learning. The proposed resource is a learning object, which uses concurrently different media, such as text, audio (sound and narration) and images. The RIMult can be used in classroom environments and in distance learning and performed both online and offline. The paper discusses...
iVDR (Information Versatile Disk Removable) is new generation large-capacity hard disk for the digital high-definition era. In this paper, it is described that iVDR has excellent performance for large-capacity storage, mobile storage, and DRM (Digital Right Management). Then a solution of iVDR' storage and encryption for Internet video is designed and proposed. And 3 formats of Internet video file,...
To enable rich communication services, mobile operators are developing various IP Multimedia Subsystem (IMS)-based technologies for they fear that their present voice and SMS business will soon be substituted by newer IP-based services from Internet companies. They reason that since the new rich communication services -- such as enhanced presence, group communication and seamless switching between...
Teachers and students use multimedia network technology very often in their everyday life in China and the technology is being used in education commonly internationally. Multimedia network technology used in higher vocational English teaching can arouse the interests of students in English learning, benefit their individualized development and benefit the building up of the student-centered teaching...
As an emerging global, Internet-based information service architecture, Internet of Things facilitates different things connecting to IP network. Using information sensing devices such as sensors, radio frequency identification (RFID), and global positioning systems and so on, Internet of Things is aimed to facilitate connection, identification, management and control between things. With growth of...
Fairy Tales exist for centuries and have intrigued educators who have been utilizing their "magical power of affection", especially when teaching young children. In the current paper, story creation is examined with the perspective of the children as authors. A web 2.0 service, Tikatok, which provides several facilities for creating stories in a book-like format, is utilized in order to...
In this paper we propose a simple pragmatic technique, called fladget, for enabling end-users to mashup multimedia content within Wiki pages of their community peers. Since the fladget considers Wiki as a content as well as mashup repository service, Wiki RESTful API is proposed. The fladget extends functionality of existing plugin mechanism, so it can use rich-client technology for interaction with...
As the rapid development of Internet, multimedia contents become increasingly dominant and voluminous in Web. Meanwhile contents duplication and redundancy become more and more common among different web sites. This bright inefficiency to our caching system, both in the utilization of cache storage and in the bandwidth cost. In this paper, we propose Content-Oriented Internet Cache Protocol (Co-ICP)...
Recently, immense multimedia information is exchanged on the Internet, where 3DCG, video, image, sound, and text are involved in various circumstances with different terminal devices, networks, and users with different knowledge and competence on using computers. This fact may easily lead to so called edigital divide' unless any special support is given to the users with few knowledge. We have already...
Voice over IP is a technology that offers voice communication service over IP-based networks. It has been in a focus of much attention in recent years. SIP, the Session Initiation Protocol is an IETF signaling protocol for session management for text and multimedia exchanges, like VoIP, instant messaging, video, on-line games and other services. Various telephony applications and services, such as...
Text data hiding is a steganographic technique different from the secrets hiding in multimedia, such as images, audio and video. Sun et al. proposed a text data hiding scheme to divide the Chinese character into left and right parts for enhancing the capacity, which is called L-R scheme. Adopting the concepts of Sun et al.¡¦s scheme, Wang et al. proposed an improved version to incorporate the up and...
IP Multimedia Subsystem (IMS) ia an architectural framework suitable for Fixed Mobile Convergence (FMC), where users can access any multimedia services ubiquitously from any (wireless or wireline) devices. IMS offers network and service providers a great flexibility and scalability to provide a wide range of modern telecommunication services. This paper addresses our experiences in deploying a small-size...
In this work a new Universal Communications Framework (UCF) is defined, based on IMS concepts and on EPC technologies. The UCF extends the IMS concepts to a generic middleware solution that intermediates between underlying network infrastructure and various application functions by offering generalized service APIs. One use case scenario to demonstrate the overall system is the integration of non...
